Herzlich Willkommen Bienvenue Welcome General Basics JUMO Screen Recorders Manfred Schleicher
Advices for the presentation This presentation shows important functions of JUMO- Screen Recoders and demonstrates their application Both LOGOSCREEN 500 cf and LOGOSCREEN nt offer the functions described The exemplifying description of configuration and operation applies for the LOGOSCREEN 500 cf Configuration and operation are slightly different from those of the LOGOSCREEN nt Most of the explanations are based on concrete examples 2
Application Example Two temperatures (PT100 each) and a pressure (4 20 ma = 0 500 mbar) shall be recorded Basicly the measured values shall be recorded every 20s. If the temperature 1 is > 100 C, the values shall be recorded every second. If a potential-free contact is closed (binary input 1), the following text shall be adopted in the event list: Ready for operation 3

Configuration of the Inputs Configuration Input 1-2 9
Configuration Inputs Configuration Input 1-2 Within the setup-program please go to the submenu analogue inputs. There your are requested to proceed as follows: Select the input you want to configure; in our example we use the inputs 1-3. Under input 1 and 2 (menu item: sensor) please select resistance thermometer. The thermometer is connected in 3-wire circuit; please take the corresponding adjustment. The correct temperature for all common resistance thermometers and thermocouples is automatically built on the basis of the measured resistance values or voltages. For a PT100 you can keep the basic adjustments under menu item linearization. Our signal shall be recorded within a range of 0 200 C; please put in the relevant limit under menu item Range. 10
Configuration of the inputs Configuration Input 3 4 ma equals 0 20 ma equals 500 11
Recording How to assign temperatures and pressure signal to the channels our devices offer a certain number of analogue- and binary channels in our example the signals of the analogue inputs 1-3 are assigned to the analogue channels 1-3 the channels 4-6 are disconnected (input signal: no signal): Configuration Dispaly at the device 12
Recording Signal binary input 1 (ready for operation) assign event trace Binary input 1 is assigned to the event trace The event traces 2-6 are disconnected: Configuration Display at the device 13
Recording Normal operation Normally the screen recorder shall record a measured value every 20 s; in the submenu Normal operation we put in the corresponding specifications Normal operation is required memory status on Storage cycle for the measured value shall be 20s 14
Recording Normal operation Memory values The screen recorder scans the input signals every 250 ms (in 20 s 80 sampling rates) Under Memory value you can define which of these 80 sampling rates shall be stored: The mean value of the 80 signals The instantanenous value The minimum value of the 80 signals The maximum value of the 80 signals The maximum and the minimum of the 80 signals (peak value) 15
Recording Event Operation and Alarms If a binary signal is active, the recorder can be changed into event operation In this case memory value and cycle can be changed In our example the recorder changes into event operation, if there is a high alarm at input 1. Peak values are still stored; however, the storage cycle for the measured values is 1 s 16
Recording High-Alarm In our example we change into the event operation, if there is a high alarm at analogue input 1 In order to configure the alarm, we must select the used channel: Text 1 is defined in the menu texts 17
Effects at the device Alarm changes into event operation, text indicated in event list The Signal Max-Alarm 1 changes the device from normal operation (Storage in the example every 20 s) to the event operation (in the example the measured value is stored every second). In the event operation the colour of the chart speed display changes to orange If the limit of 100 C is exceeded, an alarm occurs The configured text is taken over in the event list 18
Recording Time operation If e.g. the storage cycle is changed for a certain period of time, the timed operation applies In our example during the time from 20:00 hh until 06:hh the value shall be recorded every 180 s only Please make the following adjustments: 19
Recording Priorities, event operation, timed operation, normal operation If all three kinds of operation apply, the recorders are working as follows: Actual time not within the timed operation, control signal for the event operation is not active Normal operation Actual time within the timed operation, control signal for the event operation is not active Timed operation Control signal for the event operation is active Recorders work in the event operation The event operation has top priority 20
External Texts Take-over of a text as result of the binary signal If binary input 1 closes, the text ready shall be taken over in the event list: Indicate the number of the customer text which shall be taken over in the event list in the event of a positive or negative edge at binary input 1 Event list of the device: Define customer text 21
Data transfer to the device Transfer via interface alternatively In our example new data (configuration) are transferred to the device A new configuration for the LOGOSCREEN 500 cf is created 22
Operation Change of the diagram views Change of diagram views is possible with the push-button the following views are possible: channel display ; Digital display - large Diagram (without headline) Diagram with digital display Diagram with scaling Diagram with bargraph 23
Operation How to show and/or remove the event traces Event traces can be shown or removed with the push-button Event traces 24
Operation Calling the event list you can reach the event list by two possibilties: 1. Selection by push-button: 2. Menu navigation Button menu 25
Data Memory Explanation I/II To help you to understand history and operating principle of the menu Compact-Flash-Card, the following pages will provide you with important explanations about the data storage: The recorder has a flash memory which work as a ring buffer If a block of 4 Kilobyte is completed, a copy of these data is stored on the external CF-Card 26
Data Memory Explanation II/II The memory range with the copied data is considered as free memory The part of free memory is displayed on the screen for your information: 27
Operation History Function Data in the main memory can be checked with the history function: The diagram can be scrolled to certain point of time Scroll buttons Zoom is possible 28
Operation Data memory on CF-Card As mentioned already, the data are automatically copied from the internal memory to the external CF card However, this done only, if one data block is completed with 4 kb If you want to make sure that all data are on the CF-card before removing the card, please select the corresponding submenu in the menu CompactFlash-Card: 29
Further Functions Now the recoder works acc. to the requested configuration The data of the CF-Card can be evaluated with the evaluation software PCA3000 On the following pages further functions of the screen recorders are described 30
Configuration Transfer with CF-Card A configuration by setup can alternatively be transferred with the CF-Card: Read-in of the configuration in to the recoder as follows: Menu CompactFlash-Card CF-Card Config-Data 31
Configuration Transfer with CF-Card Before the menu starts, the corresponding code must be put in: The code can be changed with the setup program: 32
Relay Outputs Screen recorders can be equipped with relay outputs A multiplicity of functions can be assigned to the outputs Example: A high alarm at input 1 occurs Relay 1 switches 33
Mathematics / Logic Mathematics - Principle Max. 70 digits 34
Mathematics/ Logic JUMO-Screen recorders offer a mathematics/logic function (option with costs). With the setup-program several mathematics- and logic formula can be defined. In the formula-editor (left) you can find the variables which can be integrated in the formula. The allowed operators are indicated in the right window. All mentioned terms can be imported into the formula with Adding. In our example we will use the mathematics formula to create the mean value of the signals at analogue input 1 and analogue input 2. With the logic formula you can realize logic functions (Example: Logic 1 shall be active, if the binary inputs 1 and 2 are active). 35
Mathematics / Logic Mathematics how to enable? Mathematics/Logic for JUMO screen recorders can be released afterwards: Enter enable code (Release) Generate the code number 36
Record Mathematics In the registration the maths value is assigned to a channel: Display of the maths result at the recorder: 37
Configuration from the device front Configuration of the JUMO-Screen recorders can be realized in a big scope from the front of the device Adjustments are to be made in the menu Configuration : Works adjustment 9200; please refer in the setup to submenu instrument data 38
Display switch-off The display switch-off is energy-saving (a good portion of the power consumption is allotted to the display) and saves the display. There are two possibilities: If the user does not tap a key, the display will be switched off after a defined period (here 5 min.). After pressing a key, the display will be switched on again. As long as the control signal is activated (here binary input 1), the display is switched off. 39
Time Synchronisation In the menu Extras a new time for the screen recorder can be defined: If the time is changed, a new configuration is created Due to a binary signal the recorders can be synchronised on the clock minute: The synchronisation signals occurs on the clock minute If the time of the recorder is in the second half of the minute, the time is set ahead to the clock minute If the time of the recorder is ahead up to half a minute, the time is reset to the clock minute Time synchronisation does not create a new configuration! 40
